What temperature should I print HIPS on the Prusa MK4S?

Start at 240°C for the hotend and 100°C for the bed, then run a temperature tower across 230–255°C to dial in your exact filament brand.

What print speed works for HIPS on this printer?

Around 119 mm/s is a safe starting point on the Prusa MK4S. It can go faster once the profile is tuned, but start conservative for clean walls.

What retraction should I use?

Use about 0.8 mm of retraction (direct drive needs very little). If you see stringing, raise retraction speed before distance and dry the filament.

Do I need an enclosure for HIPS on the Prusa MK4S?

Yes — HIPS needs an enclosure to avoid warping, and the Prusa MK4S is open, so add one or expect warping and cracking on larger parts.

HIPS settings for the Prusa MK4S

Workable with mods

⚡ Quick answer: Print HIPS on the Prusa MK4S at 240°C hotend, 100°C bed, 119 mm/s, 0% part-cooling fan and 0.8 mm retraction. Run a temperature tower to fine-tune your exact spool.

These are tuned starting settings for printing HIPS on the Prusa MK4S. The Prusa MK4S has a direct-drive extruder with an all-metal hotend, so we set the hotend to 240°C and the bed to 100°C. HIPS doubles as a light structural material and a limonene-dissolvable support for ABS.

⚠️ HIPS needs an enclosure and dissolves in limonene. The open Prusa MK4S works for small parts, but expect warping on anything large.

Troubleshooting HIPS on the Prusa MK4S

Problem	Fix
Stringing or fine hairs	Dry HIPS before printing, drop the hotend a few degrees below 240°C, and raise retraction toward 1.2 mm. Damp filament is the No. 1 cause of stringing.
Poor first-layer adhesion	ABS slurry or glue; enclosure needed. Re-level the bed, set a slightly squished first layer, and wipe the sheet with IPA so it is grease-free.
Blobs, zits or rough walls	Slow the outer wall, enable coasting/wipe, and keep retraction near 0.8 mm. Keep the part-cooling fan low so layers bond and warping stays down.
